SFR.fr is the consumer email service of SFR, a major French telecom operator now owned by Altice France. The service runs standard IMAP, POP3, and SMTP with SSL/TLS on all protocols. Configure mail clients (Outlook, Thunderbird, Apple Mail, or mobile equivalents) with the settings below plus your SFR account password.
SFR has consolidated multiple French telecom brands (Numericable, SFR, Red by SFR) under one email infrastructure. Legacy addresses on @sfr.fr, @neuf.fr, @club-internet.fr, and @numericable.fr continue to work but new addresses are typically only issued for active SFR customers. If SMTP fails intermittently after network changes, verify that outbound submission is not being rerouted through a corporate proxy. Reference: SMTP 550 5.7.1 guide.
Quick Reference: SFR.fr Server Settings
Configure your mail client with the values below. Encryption is required on all three protocols.
| Protocol | Server | Port | Encryption | Authentication |
|---|---|---|---|---|
| SMTP (outgoing) | smtp.sfr.fr | 465 (SSL) or 587 (STARTTLS) | Required | Full email + password |
| IMAP (incoming, recommended) | imap.sfr.fr | 993 | SSL/TLS | Full email + password |
| POP3 (incoming, single device) | pop.sfr.fr | 995 | SSL/TLS | Full email + password |
SFR.fr SMTP Settings (Sending Mail)
SMTP handles outbound mail. Use smtp.sfr.fr on port 465 with SSL/TLS or 587 with STARTTLS. Authentication uses your full user@sfr.fr address (or the legacy @neuf.fr, @club-internet.fr address) and your SFR account password.
If port 587 times out on your network, switch to 465. Some French corporate networks and mobile carriers block outbound 587 to reduce open-relay abuse. SFR also enforces per-account send limits (typically a few hundred messages per day for consumer accounts); if you exceed the limit, submissions return a temporary 4.7.0 error and resume after the rolling window resets.
SFR.fr IMAP Settings (Recommended for Reading)
IMAP synchronizes mail across every configured device. Use imap.sfr.fr on port 993 with SSL/TLS. Authentication uses the same credentials as SMTP.
Server-side folder mapping follows the standard IMAP scheme (INBOX, Sent, Drafts, Trash). If you had a legacy Neuf or Club-Internet folder structure, the folders migrated automatically during the Altice consolidation; check subfolder subscriptions in Thunderbird if some folders don’t appear on first sync.
SFR.fr POP3 Settings (Single-Device Access)
POP3 downloads mail to a single device and removes it from the server by default. Use pop.sfr.fr on port 995 with SSL/TLS. If you want to keep mail on the server for other devices, enable “Leave messages on server” in the client’s POP3 advanced options before the first sync.
For most 2026 setups, IMAP is the better choice: it keeps the same mailbox state across your phone, laptop, and tablet. POP3 makes sense only when archiving to a single device or on very bandwidth-constrained connections.

Frequently Asked Questions
How do I recover an SFR.fr email password?
Use the SFR customer portal password recovery flow at sfr.fr. Legacy @neuf.fr and @club-internet.fr addresses use the same SFR recovery process. If the recovery email or SMS goes to an outdated contact, call SFR customer support with proof of account ownership.
Can I keep my @sfr.fr email if I leave SFR as ISP?
Yes, SFR allows former subscribers to keep the mailbox as a free standalone service (Mail SFR). No ISP contract required to continue receiving and sending mail. Enable this option in your SFR account settings before terminating your telecom contract to avoid a mailbox freeze.
Does SFR.fr support OAuth2 authentication?
No. SFR.fr supports only password-based SMTP authentication (LOGIN, PLAIN over SSL/TLS). OAuth2 is not implemented. If your account has two-factor authentication enabled, generate a mail-specific password in the SFR account portal before configuring any mail client.
Which SMTP port works if my network blocks 587?
Switch to port 465 with implicit SSL/TLS. Many French corporate networks and some mobile carriers block outbound 587 to reduce open-relay abuse but leave 465 accessible. Both ports use identical authentication with your SFR credentials.
Why do @neuf.fr and @club-internet.fr addresses use the same SFR servers?
Neuf, Club-Internet, and Numericable were absorbed by SFR (then by Altice France) during telecom consolidation in the 2000s and 2010s. The mail infrastructure was unified onto SFR servers, so legacy addresses now route through smtp.sfr.fr, imap.sfr.fr, and pop.sfr.fr with their original credentials.
About This Guide
The SFR.fr server settings on this page were last verified in July 2026 against the SFR customer support documentation and public postmaster records. Email server configurations rarely change once established; providers typically issue major updates only every one to two years, usually tied to phasing out unencrypted protocols. SMTPedia re-verifies these settings quarterly and after any announced SFR infrastructure changes. If you find a discrepancy between what is documented here and what SFR.fr currently requires, please report it so we can update the reference.
